Hello _again_,
I have a form which contains a file upload input.
I'm wondering how I tell (in php) if that file upload bit has an entry in it
on submission?
I wanted to do this:
if (!($small_image_upload == 0))
{
// small image data
$small_imagehw = GetImageSize($small_image_upload);
$small_width = $small_imagehw[0];
$small_height = $small_imagehw[1];
$small_upload_request = "1";
}
but it didn't register if a file _had_ been submitted for upload.
can anyone tell me the bit of logic that would do this?
thanks very much - dunstan
p.s. and I can't check this with JS at submission because it's optional
